7005S17PF

Overview

The Renesas Electronics Corporation 7005S17PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a density of 64 kilobits. It features an 8K x 8 organization and operates on a single 5V power supply. The device supports simultaneous independent access from two ports, enabling true dual-ported functionality without bus contention. Key electrical specifications include a maximum access time of 17 nanoseconds and a core voltage range of 4.5V to 5.5V. It is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 0.8mm pitch.

Feature Summary

• True dual-ported memory cells allow simultaneous reads of the same memory location from both ports.
• On-chip hardware support for semaphore signaling and port arbitration logic between master and slave modes.
• Automatic power-down feature controlled by chip enable signals for low standby power consumption.
• TTL-compatible inputs and outputs designed for direct interfacing with standard logic families.

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider word systems
• Battery-backed data storage requiring 2V data retention capabilities

Procurement Notes

Verify component authenticity through authorized channels due to potential obsolescence. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Ensure compatibility with 5V logic levels and check for lead-free status if RoHS compliance is mandatory for the target application.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration circuitry. Consider the 17ns access speed for moderate-frequency asynchronous interfaces. Evaluate the TQFP package constraints against available PCB real estate and thermal dissipation needs.

Part Context

This part belongs to the 7005 series of dual-port SRAMs manufactured by Renesas Electronics. The series provides flexible memory solutions for embedded systems requiring high-speed data sharing between processors. Variants in the family differ primarily in access speeds and package types, such as PGA or PLCC options.
